I’m working on a some materials for a class wherein I’ll be teaching some young, wide-eyed Windows nerds about Linux and we’re including a section we’re calling “foot guns”. Basically it’s ways you might shoot yourself in the foot while meddling with your newfound Linux powers.
I’ve got the usual forgetting the . in lines like this:
$ rm -rf ./bin
As well as a bunch of other fun stories like that one time I mounted my Linux home folder into my Windows machine, forgot I did that, then deleted a parent folder.
You know, the war stories.
Tell me yours. I wanna share your mistakes so that they can learn from them.
Fun (?) side note: somehow, my entire ${HOME}/projects folder has been deleted like… just now, and I have no idea how it happened. I may have a terrible new story to add if I figure it out.
Just recently I have skill issue’d myself by doing
git clean -rfin my home directory where my dotfiles live and therefore deleted all of my home files. I was tired and looked for a quick way to resolve my conflicts and made the stupidest mistake one can do: execute a command you do not really understand.At least I know what it does now and now I also do hourly local backups of my files with cron and borg.
